Instruction book, IQAN-MC3
CAN communication between multiple IQAN-MC3 master modules.
The IQAN-MC3 can be used for connection to sensor subsystems over CAN, assuming
that the CAN protocol is suitable for safety related communication and that the
diagnostic features in that protocol are able to be implemented on the IQAN-MC3.
CAN communication between IQAN-MC3 and other units with support for safe communication.
The diagnostic checks required by the protocol need to be implemented in the
application.
Outputs
Each individual power driver of the IQAN-MC3 uses a combination of high-side and
low-side switches to control the load, this makes it possible to have an alternative
shutdown path if one would fail.
MC3-SMR-006:A CAN communication
When exchange of safety related data on CAN is done using a protocol that is not
supported by IQANdesign, the diagnostic features of that protocol shall be
implemented in the application.
